Wide Conversion Lens for GR Series

The NiSi PR-10 is a 0.78x wide conversion lens built for Ricoh GR series cameras. It widens the native field of view to a 21mm equivalent on GR III and GR IV models and a 31mm equivalent on the GR IIIx. Street, landscape and architectural photographers gain expansive framing without changing cameras. The lens requires a model-specific 49mm filter adapter sold separately.

Optical Coating and Build Quality

Multi-layer nano coating reduces internal reflections to control flare and ghosting in strong or mixed lighting. The precision-machined aluminum alloy frame keeps the adapter light while resisting daily wear and travel stress. No power draw, cooling or noise considerations apply to this passive optical accessory.

Macro Mode and Adapter Flexibility

Full compatibility with the GR series Macro Mode allows close-up shooting while the conversion lens remains mounted. A dedicated 49mm filter adapter for each GR model enables secure attachment and maintains filter-thread access for circular polarisers or ND filters. Buyers needing a wider-than-21mm perspective or a zoom range will not find it here.

Questions about this item

How do I attach the 0.78x conversion lens to my Ricoh GR III?

Thread the 49mm NiSi filter adapter onto the GR III lens barrel, then screw the PR-10 conversion lens into the adapter's front threads; the step often missed is fitting the adapter first.

Will the anti-reflective nano coating need reapplication or special cleaning?

The coating is permanent; clean only with a blower, soft brush, and lens cloth — no solvents or abrasives are required.

At what equivalent focal length does vignetting appear on a GR IIIx?

The GR IIIx reaches a 31mm equivalent; vignetting is not reported at this setting.
